3 voltage selection switch
(may not be available on
certain computers)
Your computer is equipped with either an auto-sensing voltage selector or a manual
voltage-selection switch. Computers with an auto-sensing voltage selector do not have
a voltage selection switch on the back panel and can automatically detect the correct
operating voltage.
To help avoid damaging a computer with a manual voltage-selection switch, set the
switch for the voltage that most closely matches the AC power available in your
location.
NOTICE: In Japan, the voltage selection switch must be set to the 115-V position
even though the AC power available in Japan is 100 V.
Also, ensure that your monitor and attached devices are electrically rated to operate
with the AC power available in your location.
